PETG '2079851475616104452 in-mold pressure too high
Problembeschreibung
During PETG '2079851475616104452, the cavity pressure is too high, causing flash, mold deformation or equipment alarm.
Ursachenanalyse
Injection pressure too high, melt viscosity too low (processing temperature too high), insufficient venting back pressure, wall thickness too thin and filling resistance large.
Lösung
Appropriately reduce injection pressure and speed; lower the barrel temperature to 230-250°C; improve venting; increase wall thickness or enlarge the gate.
Wichtigste Erkenntnis
PETG in-mold pressure abnormality requires comprehensive adjustment of pressure, temperature and venting.
